GSS7765 - Interference simulation system

Comprehensive RF interference test solution

Combined with Spirent’s powerful GSS7000 or GSS9000 Series simulators, the GSS7765 interference generator creates the ultimate tool for testing against external jamming and unintentional interference. The GSS7765 enables you to create and generate custom waveforms, helping you to defend your systems against real-world threats.

Software

The GSS7765 package comprises one or more high quality commercial signal generators plus an Interference Combination Unit (ICU). The package is supported by Spirent’s SimGEM software suite. The SimGEM software supports three operating modes. Fixed mode allows a scripted series of events to be defined, while Modeled mode allows the user to position interference sources in the scenario and model the level effects as the simulated vehicle moves within the specified environment. Interactive mode enables the interference source power level and modulation characteristics to be controlled in real-time.

Realistic, real-time 3D simulation can provide the richness of detail necessary for testing GNSS receiver performance in multipath and obscuration
